Soldering, rework and desoldering tips and nozzles transfer heat to the connection point. Nozzles are typically used on hot air pencils in hot air stations to perform rework on printed circuit boards (PCB). No-vacuum nozzles come in a variety of forms to allow precise and controlled rework. These forms include round, round bent, flat, two-sides heated and four-sides heated. Soldering and desoldering tips include tips and cartridges. Cartridges heat up quickly and come in chisel, bevel, hoof and conical forms. Tips allow high heat transfer and come in chisel, round, flat, knife, micro and fine chisel forms.
